Leaching implies heap-leaching above ground using strong chemicals, a process used in gold recovery. Because In-Situ Recovery (ISR) does not use strong or caustic chemicals, but rather oxygen and sodium bicarbonate, ISR has become the common name now used to describe the process of recovering uranium through water wells.
